In the final draft script of "Charlie X", this character was initially described as "an attractive, young female crewman" and her altered appearance was referred to as "aged... many years... lined..." with her hands also characterized as "aged."

This is one of only a handful of appearances of a female crewmember wearing the late 2260s uniform with pants rather than a skirt.

She was described in the script as "a pretty Crew Woman coming down the corridor, carrying a tricorder... efficient, bent on business."

Christopher's viewpoint in this scene appears as a reaction to Star Trek's vision of the future, especially that of women serving aboard a military vessel. This was evident in the script, as that being what Christopher was most amazed at, where the script note states, upon seeing her "Christopher just stares... [...] Kirk steps in [the elevator], turns back to see Chris is still staring after the girl... not lecherous, boys... simply not believing." Once in the elevator, the disbelieving Christopher had originally said "pretty girl..." (rather than "a woman...?"), before being corrected by Kirk, before the following script note explained: "Christopher's face reads in large, indelible letters, "A CREWMAN?!" but he'd be shot before he'd voice it."

Her role was originally much larger, based on evidence in the episode's shooting script. According to a deleted scene from that script, she encountered Nomad in the corridor, where it asks her what her function is. She nervously tells it that she is an astrochemist, while in turn, it notices her fear, describing her "mixture of apprehension and an irrational desire to flee." In seeking an explanation, she angrily explains that she isn't "usually stopped in the corridors by a... chunk of metal that asks questions." Nomad then takes note of her emotions, namely her "confusion and hostility", and informs her that such "malfunctioning in units should not be allowed by the Creator." Nomad continues to press, asking her why she had "not been repaired?" She retorts, "Why haven't you?" Describing her response as "non sequitur", it informs her that she will be repaired, and as it approaches, she attempts to flee. The remained of the sequence is described in the script notes as, Nomad "fires a tiny compact ball of energy at the fleeing Crewwoman.", who is then "hit by the blob...a flash, and she disappears."
